Abstract
Abstract Automatic carton erecting and packaging machines for single blank (one part) and double blank (two part) cartons are described. Tubular bumpers are automatically formed on initially flat carton blanks in a low friction operation by folding the side flaps of the blanks over a forming bar with a series of roll over cams. The newly formed bumpers are then brought into engagement with a series of double angle wheels which simultaneously apply lateral and downward pressure to the bumpers to insure that their cross-sections form true squares or rectangles. The forming bar, the roll over cams and the double angle wheels are easily adjustable in the horizontal and vertical directions so as to accommodate carton blanks of various sizes. Also, the angular positions of the roll over cams and the double angle wheels are easily adjustable. A contoured flight which pushes the carton blank through the bumper forming and gluing operations also engages the article to be packaged and inserts it into proper position in the carton blank. In the double blank carton machine, the filled carton and its cover are simultaneously conveyed into engagement for the final gluing and closing operation. In the single blank carton machine, a rotating roll-over bar closes the carton cover as it is conveyed to the final gluing and closing operation.
